AAKK/AAJJ/AAQQ/AATT double suited or not
6789, 789T, 89TJ (suited helps)
I'm a pretty loose player though..so I"ll play a high pair if it's got an Ace or King along with it...will play double suited: Ah3hKd4d stuff like that, but position is really key..looking at what your players are raising with, ESPECIALLY at the high limits, people will try to take the blinds with crazy hands, so just try to exploit that, and you should be fine! Any two pair I'll call with..there's a 25% chance of hitting a set with two pair in your hand.
Don't really ever try to chase a flush or a straight, it can get expensive and pretty just like in Hold'em, unprofitable. Bet what you have..playing it straightforward has been the best way for me. Don't reraise, unless you are ahead, and in Omaha that's rarely ever, lol. So, keep the pots small.
